# codexloop architecture Dependencies point inward. `import-linter` enforces this in CI. ``` src/codexloop/ ├── domain/ # PURE. stdlib only. No I/O, no async, no third-party. ├── application/ # Protocol ports + use cases. Imports domain + stdlib. ├── infrastructure/ # Adapters. ONLY layer that may import openai. ├── cli/ # Typer. Calls application via bootstrap. └── bootstrap.py # Composition root — the ONE module that sees every layer. ``` ## Where does new code go? 1. Touches FS, network, clock, or an SDK? → `infrastructure/`, behind a `Protocol` in `application/interfaces/`. Never `import openai` elsewhere. 2. Pure decision, zero I/O? → `domain/`. Examples: `classify.py`, `waiting.py`, `completion.py`, `capacity.py`. 3. Orchestration (port → domain → port)? → `application/`. 4. Argument parsing / terminal formatting? → `cli/`. When in doubt, push logic inward. `lint-imports` names the broken contract. See ADR 0001.
